In general, a computer appliance is a computing device with a specific function and limited configuration ability, and a software appliance is a set of computer programs that might be combined with just enough operating system (JeOS) for it to run optimally on industry standard computer hardware or in a virtual machine.

A firewall appliance is a combination of a firewall software and an operating system that is purposely built to run a firewall system on a dedicated hardware or virtual machine. These include:

software-based firewall appliances: a system that can be run in independent hardware or in a virtualised environment as a virtual appliance

hardware-based firewall appliances: a firewall appliance that runs on a hardware specifically built to install as a network device, providing enough network interfaces and CPU to serve a wide range of purposes. From protecting a small network (a few network ports and few megabits per second throughput) to protecting an enterprise-level network (tens of network ports and gigabits per second throughput).

A firewall appliance is a combination of a firewall software and an operating system that is purposely built to run a firewall system on a dedicated hardware or virtual machine. These include:

embedded firewalls: very limited-capability programs running on a low-power CPU system,
software-based firewall appliances: a system that can be run in independent hardware or in a virtualised environment as a virtual appliance hardware-based firewall appliances: a firewall appliance that runs on a hardware specifically built to install as a network device, providing enough network interfaces and CPU to serve a wide range of purposes.
